SMT Digital Devil Saga 1 opening theme

The ORIGINAL opening theme for Shin Megami Tensei : Digital Devil Saga part 1 for the PS2.
THE Atlus JRPG that rendered me shockproof to any plot twists that I have seen in games made by Atlus today.

Hmm... should I revisit this game? This game's difficulty will EAT YOU ALIVE if you don't know how the Push Turn Battle system work.
I'm practically a veteran at this point, so I can easily manage it.
I can't say the same for the "modern audience" of today...
